Stephen Greer's ego is unpalatable to modest people of inquiry and he tells information that I confidently know is either misinformation or disinformation. However if you can ignore his non stop showing off his inside knowledge over spooks and military parasites there's some killer information in this and he also claims to have briefed Obama's people on UFO's.
Greer could just as easily be MKULTRA or part of the establishment but this interview is still a must listen. Joe Rogan is as professional and diligent as one could wish. Make up your own mind when he is exaggerating, lying, or not as informed as he likes to think. That Roswell yawn for example.
